There’s a rule in physics called the law of the conservation of energy. Energy can neither be created out of nothing, nor disappear into nothing — all it does is change forms. That sounds simple, but it confused people for a long time.
All these little outlets add up to exactly as much kinetic energy as the car had in the first place. It works out just the way the law of the conservation of energy says: energy can change forms, but can’t ever disappear.
